Backing rods – Closed cell
Closed-cell foam backing rods are crafted from low-density polyethylene foam, known for its excellent compression and recovery properties. It is available in various sizes and lengths. The round profile of the rod helps create the correct joint sealant profile, ensuring optimal movement capability.
This product is primarily used as a backing rod for horizontal and vertical expansion joints, positioned before sealant application. The backing rod acts as a bond breaker, aids in controlling joint depths for proper joint design, and reduces sealant consumption.
